What can we build in a SaaS platform?

Plans & Subscriptions

Features to manage plans (Starter, Pro, Enterprise), subscriptions, free trials, cancellations and automated recurring payments.

Master Admin Panel

Super-admin area to manage all subscribers, suspensions for non-payment, usage auditing, module activation and direct user support.

Reports & KPIs

Dashboards with vital product metrics: MRR (recurring revenue), churn, new active subscribers, resource usage and data export to Excel/PDF.
